Thanks!  Also I understand forging helps make the network stronger.  But can people with small amounts of nxt like <50000 be able to get something from it? 


If by get something you mean Nxt, then no.  Your chances of forging a block are a fraction of a percent and even if you hit the jackpot, it's likely you'll forge a block with nothing in it. 

Maybe if the guy with a lot of Nxt starts (or joins) a pool and doesn't take a share you'll get something out of it but that would really be the only way.

Having this kind of pool of course. Especially because he does not want to have piece of the cake.

Can someone give me a quick rundown of what that first transaction achieves? Why is your account more secure afterwards?
This has relevance for cold storage, since it's not possible to send NXT into a verified account that has been created solely offline. Although you can create the address easily enough and send funds to it, what's the trade-off with connecting it to the web for that one transaction and the security it brings?


I can't explain from the level of the code (I don't think that is what you want anyway  Grin ) but...

An account without an outgoing transaction has 64 bit encryption. When you send an outgoing transaction, the account number (public key) is registered on the Nxt Blockchain. This then provides the account with 265 bit encryption.

As I understand it, it is possible that 64 bit could be bruteforced within 2-3 years. 256 bit makes it practically impossible to bruteforce.

Thanks! Actually I was hoping for a little more detail Smiley
The address is something like sha256(curve25519(sha256(key))). It is presumably as easy or hard to bruteforce this regardless of whether an account has been verified. If you know the key, you have access to the account.
You must be talking about an intermediate step - a way of sending funds from an account without using its private key?

You need someone better than me to go into detail  Grin

All I know is bruteforcing a 64bit key (1.8^19 possible combinations) is much easier than bruteforcing a 265bit key (1.15^77 possible combinations). How it is actually converted between the two...? Grin

If you are on Nxtforum, the best place to post for the detail would be https://nxtforum.org/general/ and it will get picked up by the devs.

I want to help to promote the idea of leased forging pools by leasing my 50M stake to a pool with conditions:

a) leasing period - 30*800=24000 - approximately 1 month;
b) my stake will forge for free - all collected fees must be proportionaly distributed between pool members except me;
c) pool must have transparent accounting system - any participant can see in realtime (may be with some delay of 10 or so blocks) his forging progress.

The famous and mysterious Mr. 4747...888 shows up again.
For those who complain the forging income, now it's your chance to forge something decent.

Why it is so complicated? Lease to my account for one month and that's all Wink Wink Wink

EDIT: by advice of Come-from-Beyond I added fourth condition to avoid doublespending attack.

Vertcoin sub-post say's PoS is not secure,  any comments about?

In what way is it not secure? A statement like this without any explanation is just FUD, is it not?  Grin

If they use the phrase "Coin Age" in their reply, it is irrelevant to Nxt as Nxt does not use Coin Age like Peercoin and it's clones (Novacoin, Blackcoin, Whitecoin et al).

Nxt uses a new form of POS, ask if their comments relate to Nxt and we can talk more.
